Application filed March 21, 1906- Serial No. 307,207-

' zen of Canada, and a resident of Portland, in

the county of Multnomah and State of Oregon, have invented certain newand useful improvements in Candy-Machines, of which the following is aspecification.

My invention is an improvement in candymachines; and it consists incertain novel constructions and combinations of parts hereinafterdescribed and claimed.

Referring to the drawings forming a part hereof, Figure 1 is a side viewof my improve ment. Fig. 2 is an end view. Fig. 3 is a top plan view.Fig. 4 is a transverse section of the rim of the coolingwheel. Fig. 5 isa side view of a portion of the cooling-wheel and a portion of thecandy-pan. Fig. 6 is a front view of Fig. 5. Fig. 7 is a plan view ofthe receiving-table. Fig. 8 is a side view of the same. Fig. 9 is a rearview of said table. Fig. 10 is a detail side view of the operatingpawl,and Fig. 11 is a front view of the stripper.

In the practical application of my invention, I provide a frame A,comprising the side plates a, connected together by a plurality ofshafts to be hereinafter described.

A molding or cooling wheel C is secured upon a shaft 0, journaled inbearings 0 arranged upon intermediate bars a of the side plates, aportion of the periphery of the wheel projecting above the side plates.The Wheel C is provided with a relatively wide peripheral surface havinga plurality of parallel circumferential grooves 0?, and the rim of thewheel is hollowed out, as at 0 the said hollow being provided with apartition 0, having upon each side thereof openings 0 one of saidopenings being upon one side of the wheel and ihe other upon the otherside. The ends of the shaft 0 are recessed at c for the reception ofpipes c 0 and the recesses are connected by pipes 0 0 to the openings 0c in the rim. By this arrangement a cooling fluid is supplied to the rimof the wheel, the cooling fluid entering at one of the pipes 0 0circulating through the hollow rim and passing out through the otherpipe at the opposite end of the shaft.

A candy-pan B is supported upon a bracket 1), connected with the frame,and is arranged adjacent to one side of that portion I of the peripheryof the wheel which projects above the frame. The pan B is provided witha steam-jacket I), connected to a source of steam-supply by supply anddischarge pipes 19 b and is provided in its bottom with a transverseseries of openings 1), the said openings being funnel-shaped or ofgreater cross-section at their upper ends than at their lower andcorresponding in number and position to the grooves c of themoldingwheel.

A steel band D of a width equal to that of the peripheral surface of thewheel is arranged to travel in contact with that portion of theperipheral surface of the wheel within the frame, the said band beingmounted upon a series of rollers 61, d, cl, d, and d, journaled in theframe. The roller d is secured to a shaft (1 journaled in bearings (1mounted upon the upper edges of the side plates adj acent to thecandy-pan, and the roller (1 is secured to the shaft d journaled inbearings d at the upper front corners of the frame.

The roller d is journaled upon a shaft (1 supported by arms (2 of arock-shaft 0Z journaled in bearings (Z at the lower front corner of theframe, the said shaft being provided with a substantially horizontal armd upon which is movably mounted a Weight (1 The above-describedmechanism, including the roller (1, is a tension device for the steelband D. The roller d is secured to the shaft (1 journaled in bearings dat the lower rear corner. The roller (1 is secured to a shaft (Zjournaled in bearings d" in brackets (1 secured to the upper rearcorners] of the frame, the said shaft being also provided with aratchet-wheel (Z to be hereinafter described. The steel band is arrangedin contact with that portion of the peripheral surface of themolding-wheel below the up per edge of theframe and'passes over therollers d, cl, d, d, and d.

A stripper E, comprising a curved plate 0, having on its free end aplurality of fingers e corresponding in number and position totliegrooves on the molding wheel, is secured to brackets e connected withthe frame adjacent to the point where the band D leaves the peripheralsurface of the molding-wheel to pass outwardly over the roller (1,-the'fin gers of the stripper extending into the grooves of themolding-wheel for deflecting the cooled strips of candy from the saidgrooves. The strips of cooled candy follow the course of the brackets61, the outer end of the table being provided with depending arms ithaving friction-rollers h, for a purpose to be hereinafter described.The edge of the table adj acent to the roller d has secured thereto astripping-blade h the said blade having its free edge resting upon thebandD to strip the candy therefrom. The strips of candy passing out frombetween the cloth belt and the steel band D are received within thegrooves of the table and move outwardly therein. A knife K, comprisingan endless steel band, is supported upon horizontally-arranged pulleyslc 7c, secured to the shafts 1c" 7r", journaled in bearings k uponbrackets k projecting laterally from each side of the frame, the upperend of the shaft lc being provided with a bevel-gear lc meshing with agear-wheel k upon a transverse shaft is, journaled in bearings k uponthe bracket k arising from the frame, the outer end of the shaft beingprovided with fast and loose pulleys k k for a purpose to be hereinafterdescribed. The rear run of the endless bandknife passes immediatelyabove the outer edge of the table H, and the said table is lifted tobring the strips of candy passing over the said edge into contact withthe knife at predetermined intervals by means of camwheels 77, engagingthe friction-rollers h in the depending arms h The cams k are securedto-a shaft 7c, ournaled in bearings k upon the side plates, the saidshaft being also provided with. a pulley 7c", connected by a elt k witha pu ley h upon the transverse shaft k a The molding or cooling wheel Cis driven by the steel band D, which in turn is driven from the rollerdby means of a pawl engaging the ratchet-wheel d and pivoted to thepawl-lever 7c, the said pawl-lever having an eye 7c? engaging the shaft(Z and having in its lower end a friction-roller 7e engaged by a cam 76upon the shaft Z6 The pawl k is normally maintained in contact with theratchet-wheel by means of a spring 7e arranged between the pawl and thebracket k upon the pawl-lever.

At the rear of the machine is arranged a transverse conveyer M, havingits upper run on a level with the table H when said table is in itslowered position, the said conveyer be ing supported and driven in anysuitable manner and adapted to receive the candy. as it is pushed fromsaid table.

In operation the candy is introduced-into the pan B in a plastic state,it being maintained in this condition by the steam-jacket. The plasticcandy passes out through the funnel-shaped openings in the bottom of thepan into the grooves c of the cooling-wheel. The transverse shaft h isdriven in any suitable manner and imparts rotation to the shaft 7cthrough the belt 7c By means of the pawl and ratchet intermittent motionis imparted to the shaft d, which in turn imparts an intermittent rotarymotion through the steel band D to the moldingwheel. The strips of candyare retained in the grooves during the movement of the wheel by thewheel-band D and are cooled by the cooling fluid circulating through thehollow rim of the wheel. When the candy reaches the stripper, the stripsare deflected from the grooves and pass upwardly from the roller d tothe table H, the strips being retained in proper position with respectto the roller by the cloth band. As the strips are pushed forwardintermittently over the table the said table is lifted at predeterminedintervals to sever the strips transversely, the length of the piece cutoff being proportionate to the extent of each intermittent motion of themolding-wheel. When the pieces of candy are severed from the strip, theydrop onto the conveyer M, by which they are removed from the machine. Itis sometimes desirable to provide a cooling means for the belt G, andfor this purpose I arrange a hollow casing N adjacent to the said bandbelow the cooling wheel, the casing conforming to the shape of the bandand being arranged in contact therewith. The casing may be supplied witha cooling fluid from any suitable source by means of the supply anddischarge pipes n W. While I have shown the casing as being applied tothat part of the band in contact with the coolingwheel, it is evidentthat the said casing might be arranged to contact with the horizontalportion of the band or with either of the vertical portions thereof.

It will be evident from the description that considerable time and laboris saved in the use of my machine, since long exposure of the candy isnot necessary to cool it nor is it necessary to size the strips.Every'portion of the candy is utilized, there being no waste of anykind. The strips are also of uniform size throughout, and since they arecut at regular intervals the completed product is in the most convenientform for wrapping by the automatic wrapping-machine. While I have shownsquare grooves in the pan, it is obvious that the said grooves andopenings might be of any other desired shape.

Having thus describedmy invention, what naled at the corners of theframe, a tension r to the hollow rim, a band partially encircling Iclaim as new, and desire to secure-byLetters Patent, is
